What do they think is at the end of the universe?

ianp622, thanks.

I now understand that what is not understandable can be possible anyway.

Are we sure that time is a dimension? I read a book on string theory once and it was incomprehensible to me.

If you need to meet a person, you need four dimensions: Three deal with a position in space and one deals with a specific time.

Big Bang Cosmology demands finite space. Spacetime was infinitesimal, and has been expanding since t=1. The evidence for this is the expanding, accelerating universe, and in order for space to be infinitely large you must invoke some kind of steady-state theory. This is not anything close to accepted and you will struggle to find three astronomers who will tell you that space goes out into infinity in all directions at any point in time.
.

I feel like we're talking about two different things.

I refer you here.
Note the differing theories of what a multiverse is.

As for the big bang, it is finite, relative to what we postulate to be the beginning of the universe 13.7 billion years ago and there is no quarrel there.

It doesn't answer the question of what existed before the big bang, which I understand is entering the realm of the highly speculative branch of cosmology.


But I don't believe that is all there is, nor rule out, there weren't multiple big bangs. Which again refers to the infinite universe.

I'm a firm believer in "everything that has a begining, has an end."

But this is space we're talking about. All kinds of crazy shit happening up there/out there. I'm more focused on the easier question of: is there any other life out there, like us?

Yes, time is a dimension. Its one of the fundamental parts of relativity. Its why as you speed up, time slows down, which has been proven by experiments.

Pretend you have a car that travels at 100 kilometers per hour. Always. Say you start driving 100 kph West. But then you decide to go northwest instead, so you turn the wheel. Now maybe you're going 100 kph northwest, but what that really means is that you're going saaaay 25 kph north and 87 kph west. (25 squared + 87 squared = 100 squared, pythagorean theorem). As you change directions, some of your speed from going one direction gets transferred into the other direction.

Now replace north and west with space and time. We are all strapped in cars going at the speed of light. If we could remain perfectly still in space, we would be travelling through time at the speed of light. The faster we move in space though, the more has to be allotted, and so the slower we move in time. And this is true. They've accelerated atomic clocks and seen a slight delay in the recorded time when they check them.
 
The frustration thing about speculating on the inside of a black hole or anything beyond our observable bubble of the universe is we will never - ever - know for sure.

I've read about wormholes and they try to explain it as a tube through a folded over piece of paper. I know that is not literal but rather an example to try and understand what is going on. I've also heard some say the universe is like the surface of a doughnut.

So you're saying it is just in the nature of the universe, that it has an extra form that is difficult for us to understand? Where earth might seem flat to someone walking along, it is actually a sphere, and likewise the universe may seem like an expanding sphere you travel around within, but the rules actually function differently from something that simple?

If that is the case, all this distance between us and other things is mostly just perspective, and there may be a way to shortcut through the "distance" we perceive?


Tell me everything you know about Wormholes and the wormhole weapon

We live in a flat universe, that has edges. On the 2 dimensional film that wraps around the edges, is a copy of everything that is going on within the universe. The world that we experience in 3d may or may not be real. Beyond that 2 dimensional film, is hyperspace. A place where other universes, which may be very similar, or very different, float around folded up into higher geometric dimensions, occasionally colliding into each other and creating even more universes. Sitting on the edge of 10 dimensional hyperspace is a really great restaurant. As you can see it's already pretty well known, you better get in your reservation whilst you can.
 
Reflections of energy, matter and dimension propagating amongst the entity creating inter dimensional connections and pathways, hyperkinetically distributed fractionally through optimum source nodes from a primary singularity both existing and not existing within the system. The fluctuation allows for the expansion you comprehend, but is more responsible in balancing entropy from outside the system; which is a product of our system which functions as the previously mentioned singularity. As best as I can describe it.
